How instal ue4

when i run the ue4 the visual show this: UE4Editor.exe has triggered a breakpoint
how could i fix this

Hey Mahdi_Thg-

Are you able to right click on the UE4 project on the right and select build? If that completes you should be able to go the folder where the .sln is located and go into the Engine/Binaries/Win64 folder and find UE4Editor.exe to launch the editor.
